Abstract
A system for monitoring potentially hazardous conditions in an area. The monitor system provides a continuous check of the atmosphere in a given area for nuclear radiation hazard and for combustion hazard. When a predetermined radiation level or combustion condition occurs in the area an alarm is activated which indicates the particular kind of danger existing. A small bomb calorimeter housing or vessel supports and houses a radiation sensor and a combustion sensor. Detection circuitry responds to the radiation and combustion sensors to provide an output signal when a predetermined, dangerous threshold condition exists in the area. A screen capacitor, electroscope, and a periodic charging circuit comprise the radiation hazard detection circuitry. A reflex surge generator comprised of a sparking circuit and a spark gap in conjunction with a resistance thermometer detector provide the fire hazard circuitry. Indicator or annunciator circuitry coupled to the detectors disclose the status of the two circuits. A percentage of prevailing atmosphere is controllably forced through a portion of the container and continuously sampled to indicate potential fire and nuclear hazards.
